Abstract:

AbstractRadio-telemetry is a relatively new technology that is having powerful impacts on the way wildlife is studied. With tens of thousands of new radio-telemetry units produced each year, to be placed on animals in the wild, it is a technology that is becoming increasingly pervasive. This paper begins by examining the way radio-telemetry has been adapted for the study of macaws in Latin America. The paper argues that as a form of surveillance and monitoring, radio-telemetry illustrates some ways in which Michel Foucault's concepts of "biopower" and surveillance can be applied to the management of wildlife. Additionally, as the new technology creates a greater sense of distance between the "sign" of a creature and its actual reality, wild animals seem to become what Jean Baudrillard terms "simulations", in which they are increasingly signs of their own disappearance—both as creatures and as species.

Abstract:

Abstract In this study, the performance of the Long-Range (LoRa) communication and 3DR Radio Telemetry modules was evaluated. The suitability of these two communication options was assessed for the application on an autonomous sailboat prototype. The communication range and power consumption of each module are the primary factors for selection. The test results found that LoRa technology can send data stably with a range of up to 10.5 km, while the 3DR Radio Telemetry module can only send data stably up to 300 m. The LoRa technology consumes 9.56 Wh of electrical energy per day for the autonomous sailboat application, while the 3DR Radio Telemetry consumes 11.07 Wh of electrical energy per day. It was decided that LoRA technology would be implemented on the autonomous sailboat.

Abstract:

This paper presents the design and development of a VHF telemetry Two-way radio device network downtime/uptime alerting prototype. Telemetry network monitoring using VHF 2-way radio Streaming is a paradigm in networking management that has not been deployed. The framework enables continuous monitoring of the mobile and fixed access points of the mining fleet management Wi-Fi system (in the case of the Barrick Lumwana mine, Zambia). Considering the significance of real-time alerts in a mining facility, critical systems such as slope monitoring radars, mobile emergency alerts, and timely copper production reports must be monitored in real-time. The results for the performance warnings of the telemetry access points collectively accounted for a response alert time of 1999ms from the samples collected which translated to 0.29% compared to the SNMP system that registered a total of 689500ms for the samples collected which translates to 99.71% of the total response time of 691499ms. The results derived from the VHF 2-way radio telemetry prototype show that this system performs better than the traditional SNMP network monitoring system. We recommend that this IP network prototype is used in open-pit mines alongside Motorola telemetry two-way radios.

Abstract:

We examined the effects of investigator activity on hatching rates of radio-marked wild female Mallards (Anas platyrhynchos), and evaluated the efficacy of radio-telemetry to minimize nest disturbance, characterize vegetation at nest sites, and mark nests for later relocation. Differences in hatching rates between birds that were flushed once (experimental) and those never flushed (control) approached significance (P = 0.086). However, hatching rates did not differ (P = 0.588) between the two groups when nests where investigator activity caused abandonment (30% of experimental nests) were removed from analysis. If the nest remained active, flushing the bird and visiting the nest once did not appear to increase the likelihood of the nest being depredated. We were able to locate 92% of radio-telemetry marked nests (control) after the female was no longer tending the nest. Radio-telemetry provides a technique to collect relatively unbiased nesting data for Mallards without disturbing the female.

Abstract:

Two groups of pygmy marmoset (Cebuella pygmaea) were rescued along the left bank of the Madeira River during the formation of Santo Antônio Hydroelectric Dam reservoir in the state of Rondônia, Northern Brazil. Reintroduction of both groups occurred in areas of open Tropical rainforest located within the project´s Permanent Preservation Area. A post-release monitoring was conducted for three months using radio-telemetry. Individuals of each group remained together and settled in stable home ranges near their respective release sites. The mortality rate of translocated animals was about 7%. This seems to be the first report documenting the complete group translocation of C. pygmaea and the first to successfully employ radio-telemetry techniques in monitoring this species. This study demonstrated the feasibility of translocation and the use of radio-telemetry in monitoring C. pygmaea.

Abstract. The data on radio telemetry links (for water information) at VHF/UHF in Hokkaido are used to investigate the rate of disturbances on radio links (or connection failure) and its association with a huge earthquake, Tokachi-oki earthquake on 26 September 2003. Especially, the telemetry links at the Tokachi region closest to the earthquake epicenter, showed a significant increase in disturbances on radio links two weeks to a few days before the earthquake on the basis of analysis during a long interval from 1 June 2002 to 3 November 2007 (over 5 years). We suggest that these severe disturbances in VHF/UHF telemetry links are attributed to the generation of seismogenic VHF/UHF radio noises (emissions). Based on this idea, we have estimated that the intensity of these seismogenic emissions is on the order of 10–19 dB μV/m. Finally, the present result was compared with other physical parameters already obtained for this earthquake.

The summer daily activity of the Radde hamster was studied using radio telemetry and the FAIS system. It is shown that the daily activity of the Radde hamster varies significantly from May to August for both males and females, which is associated with different tasks solved by hamsters in each month. Due to the behavior of the Radde hamster, the radio telemetry method does not allow us to get a reliable picture of daily activity.

Abstract:

Currently, telemetry appeared as a common method to reveal home range and movement of animal. However, the telemetry method was not applied for small-clawed otter yet. We have spent efforts to use the telemetry methods from March to August 2016 in a rice field landscape in Lubuk Alung district, Padang Pariaman regency, West Sumatra. We trapped individuals of small-clawed otters (Aonyx cinereus) using leg-hold traps and box traps. We implanted radio transmitter intraperitoneally. Movement of the animal was recorded using triangulation methods. Two male individuals of small-clawed otters were captured. One individual died soon after the transmitter implantation and another individual was successfully implanted and released. However the individual were detected for 28 hours only. In this paper, we described the efforts and problems appeared from the trapping, transmitter implantation, releasing and radio tracking process.

Abstract:

To deal with the power shortage of the implantable radio-telemetry system for animal physiological parameters dictation, a wireless power transmission system based on electromagnetic induction is proposed. The parameters of the couple coils are optimized considering the safety and stability of this power transmission, transmitting coil of rectangle section solenoid and three-dimensional receiving coil are selected. Experiments show that at least 150mW power could pick up on the load in a volume of Φ10.5 mm×11 mm with a transmission efficiency of 2.56%. Vivisection experiments verified the feasibility of the integrated radio-telemetry system based on this power supply technology.

Full text

Abstract:

Reptiles are often ignored or under-studied in freshwater systems. An understanding of their biology and thus their role in aquatic communities can be greatly advanced by studies using radio telemetry. In turn, the value of radio telemetry for research depends on the availability of suitable and reliable methods of attaching or implanting radio transmitters. The present study describes transmitter attachment and implantation techniques for selected freshwater reptiles, including the eastern and northern long-necked turtles (Chelodina longicollis and Chelodina rugosa, respectively), the pig-nosed turtle (Carettochelys insculpta), Mertens’ water monitor (Varanus mertensi) and the water dragon (Physignathus lesueurii). The effectiveness of the methods for each species is described and the potential pitfalls and challenges of each method are discussed. The literature abounds with techniques for attachment and implantation techniques, and the methods used in the present study are not wholly novel. The aim, however, is to provide detailed summaries, in one paper, of effective methods for attachment and implantation of radio-tags for freshwater reptiles with a diversity of sizes, shapes and attachment surfaces. Despite the focus on Australian freshwater reptiles, these methods are applicable to aquatic reptiles worldwide.

Abstract:

The potential for telemetry data to answer complex questions about aquatic animals and their interactions with the environment is limited by the capacity to store, manage, and access data across the research community. Large telemetry networks and databases exist, but are limited by the actions of researchers to share their telemetry data. Promoting data sharing and understanding researchers’ views on open practices is a major step toward enhancing the role of big data in ecology and resources management. We surveyed 307 fish telemetry researchers to understand their perspectives and experiences on data sharing. A logistic regression revealed that data sharing was positively related to researchers with collaborative tendencies, who belong to a telemetry network, who are prolific publishers, and who express altruistic motives for their research. Researchers were less likely to have shared telemetry data if they engage in radio and (or) acoustic telemetry, work for regional government, and value the time it takes to complete a research project. We identify and provide examples of both benefits and concerns that respondents have about sharing telemetry data.

Abstract:

Point Torment, an area of low-lying tidal mudflats and adjacent coastal peninsula, was the site of a seismic survey unique to Australian geophysical exploration. This survey was conducted by Esso Australia Ltd and the area, part of EP 104, is located north of the township of Derby in Western Australia.Surface conditions in the area varied from thickly wooded grassland on the peninsula to open mudflats. Vehicle access to the mudflats was severely restricted and helicopter support was necessary to maintain the seismic operation throughout. The operation was extremely labour intensive; for example, line-cutting through mangrove areas was carried out by hand.Seismic recording was achieved using an OPSEIS* 5500 digital radio telemetry system. With this system data is collected by portable field units labelled Remote Telemetry Units (RTU's) and subsequently retrieved by Radio telemetry and permanently stored on magnetic tape by a Central Recording Station (CRS). This was the first instance of this system being employed in Australia.

Abstract: Two adult male pumas were captured and monitored via radio-telemetry on the Colima volcanoes, western Mexico. One male occupied the western, north, and eastern slopes of the volcanic complex, whereas the other male was only located on the northeastern and eastern slopes of the volcanoes. Neither of the two males occupied the southern flank of Colima volcano. The two males were never found within close proximity to each other, although occasionally they visited the same localities. Both cats were most frequently located within humid pine-oak forest between 2,300 m and 2,900 m and were never recorded above 3,300 m. An estimated minimum density of 0.9 adult pumas/100 km2 was obtained for the Colima volcanoes. Key words: Puma concolor, Colima volcano, radio-telemetry, movements.

Abstract:

<p>Cognitive radio technology is a promising way to improve bandwidth efficiency. Frequency which is not used in any aspect will be utilized by using some of the most powerful resources in this cognitive radio. One of the main advantages of cognitive radio signal is to detect the different channels which are there in the spectrum and it can modify the frequencies which is utilized frequently. It allows the licensed users to gain the licensed bandwidth under the condition to protect the licensed users from harmful interference i.e., from secondary users. In this paper, we would like to implement cognitive radio using the beamforming technique, by using power allocation as a strategy for the unlicensed transmitter which is purely form on the result of sensing. It is on the state of the primary user in a various cognitive radio network whereas the unlicensed transmitter gives a single antenna and it modify its power transmission. For the cognitive radio setup, we have used normalized adaptive learning algorithms. This application would be very useful in medical telemetry applications. Nowadays wireless communication plays a vital role in healthcare applications for that we have to build a separate base. It reduces the effort of the building of separate infrastructure for medical telemetry applications.</p>

Full text

Abstract:

AbstractTo gain information on the microhabitat use, home range and movement of a species, it is often necessary to remotely track individuals in the field. Radio telemetry is commonly used to track amphibians, but can only be used on relatively large individuals. Harmonic direction finding can be used to track smaller animals, but its effectiveness has not been fully evaluated. Tag attachment can alter the behaviour of amphibians, suggesting that data obtained using either technique may be unreliable. We investigated the effects of external tag attachment on behaviour in the laboratory by observing 12 frogs for five nights before and five nights after tag attachment, allowing one night to recover from handling. Tag attachment did not affect distance moved or number of times moved, indicating that the effects of tag attachment are unlikely to persist after the first night following attachment. We then compared harmonic direction finding and radio-telemetry using data collected in the field. We fitted rainforest stream frogs of three species with tags of either type, located them diurnally and nocturnally for approximately two weeks, and compared movement parameters between techniques. In the field, we obtained fewer fixes on frogs using harmonic direction finding, but measures of movement and habitat use did not differ significantly between techniques. Because radio telemetry makes it possible to locate animals more consistently, it should be preferred for animals large enough to carry radio tags. If harmonic direction finding is necessary, it can produce reliable data, particularly for relatively sedentary species.

Abstract:

Abstract The occurrence of the 4–6 July 2019 Mw 6.4 and Mw 7.1 Ridgecrest earthquake sequence provided the first full-scale test of the network and telemetry readiness of the Southern California Seismic Network (SCSN), to support the ShakeAlert earthquake early warning (EEW) system in California. ShakeAlert is a U.S. Geological Survey (USGS)-led collaboration to detect earthquakes and, when possible, to alert the public before the arrival of the strongest shaking. The SCSN performed well in its regional monitoring role for both the 4 July Mw 6.4 and the 6 July Mw 7.1 earthquakes. In the EEW role, it provided timely delivery of 5 s of P-wave data to ShakeAlert, which issued its first alert 6.9 s after origin time. Data delivery at peak data volumes for many stations exhibited some latency, and, as a consequence, some data arrived too late for analysis by one of the EEW algorithms. We find that the average link bandwidth for each station was sufficient, because all waveform data were delivered automatically to the archive, but link capacity for many stations was insufficient for peak demand. We describe the performance of the data telemetry for the sequence, including cellular, radio, hybrid, and backhaul systems. Cellular-based telemetry systems maintained low latency throughout strong shaking and after, but some stations, even at great distances, experienced subsequent brief increases in latency. Performance of radio links depended mostly on the signal strength of the link, with short-distance direct shots to high-bandwidth backhaul systems showing no latency impact, whereas stations on some long distance or marginal quality links suffered latencies of tens or hundreds of seconds. Improvements are being implemented to move telemetry links onto USGS and partner high-bandwidth microwave systems, and to reduce dependency on less robust long-distance radio shots.

Abstract:

Telemetry from prosthetic systems is useful in aiding the users and clinical team in setting up and training and monitoring in the use of a prosthesis. The different forms are discussed and a new radio frequency based telemetry system is described. This system uses a computer to display the data and a video mixer to place the information on the same screen as the image of the user so that their actions and control signals can be simultaneously recorded for later study.

Abstract:

The operational equipment of the Security and Rescue Team (Matan) of the Paskhas Command Battalion called the Integrated Personal Protection (IPP Set) is currently incomplete because monitoring of the implementation of the Matan Team's activities is limited to reports through radio / HT communication tools, so that in decision making actions by the Operations Commander Puskodalops is not optimal and accurate according to the conditions in the field. Therefore we need a system that can monitor the movements of the Matan Team that can monitor the position and visual forces in real time. This monitoring system using radio telemetry can transmit data in the form of GPS coordinates displayed by Google Map as well as visual image data recorded by FPV cameras in realtime using the 3DR telemetry transmission system 433 Mhz and VTX 5.8 Ghz mounted on a tactical helmet and received by ground station receiver antennas at Puskodalops, so that the position of the matan team personnel can be monitored and conditions in the field can be monitored in realtime so that the Operations Commander can make decisions more quickly, precisely and accurately according to field conditions.Keywords : Telemetry, Security and Rescue Team (Matan)

Abstract:

Radio telemetry is used as a major way on monitoring flight test of airplanes. As information transition channel is disturbed or interrupted significantly during the blackout area during flight, the carrier information will not be transmitted normally. However, the airplane data during the blackout period has to be monitored seriously. This issue can be resolved by building re-issued data memory function into a telemetry system. This paper looks at the research of re-issued data memory technology and proposes a new design of re-issued data memory circuit for realizing the negative trigger delay storage of data flow in telemetry system during blackout period. The delayed data in the storage will be transmitted again later. The new designed circuit uses multiple re-issued data memory methods to satisfy the requirements of different telemetry tests and measurements, assuring complete data during airplane flight test.

Abstract:

To communicate with the ground station, nano satellite requires a communication system that serves in real time to regulate the procedure with ground station. One of the missions of nano satellites is the retrieval of telemetry data from sensors that transmitted using APRS technology (Automatic Packet Reporting System). We designed a prototype to monitor sensor by utilizing the APRS. Real-time sensor data was transmitted to monitor through radio using AX.25 protocol. On the transmitter side, an APRS Tracker integrated with a microprocessor ATMEGA 1284P to modulate the AFSK signal. The existence of this AFSK signal is used to transmit and receive telemetry data using handy talky. We use a computer with AGWPE software to demodulate the AFSK signal and UI-View32 to show the telemetry data. The results showed that the telemetry data can be displayed on the receiver side and acquired in real time. The accuracy of temperature sensor received by the receiver is 92.97%, and humidity sensor is 90.57%. There was a delay of 1 second for the reception of telemetry data directly.

Abstract:

Abstract I used mark-recapture analysis and radio telemetry to characterize winter movement patterns of six grassland sparrows in southeastern Arizona. Mark-recapture data were generated by banding birds captured during repeated flush-netting sessions conducted on a series of 7-ha plots over three consecutive winters. This resulted in 2,641 captures of 2,006 individual sparrows of the six species. Radio telemetry was conducted concurrently on 20 individuals of four of these species. Recapture data and radio telemetry indicated that Cassin's Sparrow (Aimophila cassinii) and Grasshopper Sparrow (Ammodramus savannarum) were the most sedentary, followed by Baird's Sparrow (Ammodramus bairdii), Vesper Sparrow (Pooecetes gramineus), Savannah Sparrow (Passerculus sandwichensis), and Brewer's Sparrow (Spizella breweri). Grasshopper, Baird's, Savannah, and Vesper sparrows tended to remain within fixed home ranges during winter. With the exception of Savannah Sparrows, whose movement behavior varied among study sites, movement patterns remained constant within species across years and study sites despite radical fluctuations in the absolute and relative abundances of all species. Interspecific differences in movement pattern suggest that species in this system partition niche space according to the regional-coexistence mechanism. Abundances of the most sedentary species, Cassin's, Grasshopper, and Baird's sparrows, were poorly or negatively correlated with summer rainfall at the between-year landscape scale, whereas abundances of the more mobile Savannah, Vesper, and Brewer's sparrows were strongly positively correlated. This is consistent with the theoretical prediction that movement constrains large-scale habitat selection, favoring mobile species in fragmented environments.

Abstract:

We first very briefly introduce the major radio facilities for astronomical research in China, and then report on the present interference situation at major radio observatories. Some of the radio interference problems are caused by paging services, mobile phone satellites, telemetry services for power supply, waterpower and earthquake activity, or radar systems, but some causes are unknown. In the worst case, harmful to radio astronomy, the Sesan VLBI station has not been able to do any observations at 92 cm due to serious radio interference problems since 1992. Still more serious interference coming from satellites can be expected in the next decade. International efforts on frequency protection should be urgently pursued if ground-based radio astronomy is to survive.

Abstract:

Radio-based signalling devices will play an important role in future generations of remote patient monitoring equipment, both at home and in hospital. Ultimately, it will be possible to sample vital signs from patients, whatever their location and without them necessarily being aware that a measurement is being taken. This paper reviews current methods for the transmission by radio of physiological parameters over ranges of 0.3, 3 and 30 m, and describes the radiofrequency hardware required and the carrier frequencies commonly used. Future developments, including full duplex systems and the use of more advanced modulation schemes, are described. The paper concludes with a case study of a human temperature telemeter built to indicate ovulation. Clinical results clearly show the advantage to be had in adopting radio biotelemetry in this instance.

Abstract:

This paper describes for the first time the possibility for recording the systolic pressure (SPI, diastolic pressure (DP), and the mean arterial pressure (MAP) as well as the heart rate (HR) and locomotor activity (LA) in freely moving mice, using a commercially available telemetry and data acquisition system. The system comprises a new, small radio-telemetry transmitter implanted in the peritoneal cavity, a receiver board placed underneath the home cage, a multiplexer and a computer-based data acquisition system. The signals from the receiver were consolidated by the multiplexer and were stored and analysed by the computer. The telemetered pressure signals (absolute pressure) were corrected automatically for changes in atmospheric pressure measured by an ambient pressure monitor. The effects of implantation on animal behaviour, and, after the animals had recovered, the effects of handling on the SP, DP, MAP and HR were examined. The radio-telemetry system for recording the SP, DP, MAP and HR provides an accurate and reliable method for monitoring the direct effects of handling on SP, DP, MAP and HR. In addition, by using this new blood pressure (BP) transmitter, we maintain that BP measurements in freely moving mice are more efficient, reliable, and less labour-intensive than the measurement techniques described in the literature thus far.
